The value of the acoustic analysis of pathological infant cry and breathing noise in everyday practice

During a period of twenty years [1969-1988] the author has observed 614 cases of congenital malformations and noninflammatory diseases of the larynx in infants and young children, Budapest. He summarizes the most characteristic symptoms of laryngeal pathology in infants, and discusses the diagnostic possibilities. Among the latter, spectrographic analyses complemented by auditory evaluation of pathological cry and different breathing noises play an important role. Based on his investigation author differentiates 20 kinds of pathological crying sounds and 4 basic forms of stridor. He describes the acoustic attributes of different pathological sound phenomena and summarizes characteristic voice changes.     

Flexible and floating choroid plexus cyst of the third ventricle: an ultrasonographic video documentation

Introduction Choroid plexus cysts can lead to isolation of the lateral ventricles and distension of the third ventricle. We present an ultrasonographic video documentation of an infant with variably shaped and localized choroid plexus cyst of the third ventricle. Case report An infant had periods of increased intracranial pressure with changing dilatation of the first to third ventricle. Cerebral ultrasonography of the not crying boy demonstrated a choroid plexus cyst limply hanging down from the roof of the third ventricle to the beginning of the aqueduct of Sylvius. During crying, the cyst prolapsed from the third into left lateral ventricle and was strangled by the foramen of Monro. Endoscopic cyst fenestration and third ventriculostomy continuously solved the problem of intermittent hydrocephalus occlusus. Conclusion Depending not only on localization and size but also on cyst form and cerebrospinal fluid pressure, a single choroid plexus cyst can cause various obstructions of cerebrospinal fluid pathways.     

脐血铅水平与妊娠结局及影响因素的关系

目的 :了解本地区脐血铅水平现状及其妊娠结局与妊娠并发症 ,新生儿体格发育及神经行为发育的关系 ,并探讨脐血铅与环境因素的关系。方法 :采用 HB2 10 0原子吸收光谱仪用原子吸收法测定 178例经剖宫分娩的新生儿脐带血水平 ,同时观察孕妇妊娠与分娩期有无合并症与并发症 ,并于新生儿出生后即刻测量体重、身长 ,2 4 h内测量头围、胸围和腹围 ,采用神经行为发育量表 ,对出生后 4 2 d的 5 0例婴儿进行神经行为发育评分。同时对产妇家庭环境等相关因素进行问卷调查。结果 :178例脐血铅最高值 12 2 μg/ L,最低值 1μg/ L,中位数 36 μg/ L,脐血铅≥ 10 0 μg/ L 者 6例 ,占3.33%。脐血铅水平与妊娠并发症无明显相关性 ,与新生儿体格发育及神经行为发育评分无明显相关性。新生儿血铅水平与环境因素 (家庭住址、居室新旧、家庭经济情况、职业等 )差异有显著性 ,P<0 .0 5。结论 :本组脐血铅水平与孕期并发症及新生儿体格发育及神经行为发育评分无明显关系。脐血铅水平与环境因素有关。     

间接免疫荧光法检测婴幼儿急性下呼吸道合胞病毒感染的特异性IgM

本文对1984年1～3月和1985年3～8月共107例急性下呼吸道感染的住院患儿,采用间接免疫荧光法检测其急性期血清抗RSV特异性IgM抗体,并与病毒分离和/或中和试验比较,敏感性为82.1％,特异性为71.8％。RSV感染患儿发病后3天内大多数病例即可从血清中检测出RSV-IgM,因此该法具有早期诊断价值。     

新生儿骨矿质含量及影响因素的研究

应用双光子及单光子吸收测定技术，检测了９２名出生３ｄ内的新生儿骨矿质含量，其中巨大儿３０名，正常体重儿３２名，低出生体重儿３０名，其孕龄分别是４０．１±０．７、３９．１±１．５和３７．４±１．２孕周。结果表明，巨大儿、正常体重儿、低出生体重儿的全身骨矿质含量分别是１０１．６±２８．８、８５．２±１９．８、５９．９±２７．２ｇ／ｃｍ２，巨大儿骨矿质含量最高，正常体重儿次之，低出生体重儿最低，差异有显著性（Ｐ＜０．０１）。颅骨、肱骨、股骨的骨矿质含量与全身的骨矿质含量有高度的相关性，相关系数分别是０．９４３、０．８７９和０．７４５（Ｐ＜０．０１）。全身的骨矿质含量与出生体重、孕龄及头围有高度相关性，相关系数分别是０．７５５、０．５９６和０．５５６（Ｐ＜０．０１）。提示颅骨、肱骨及股骨的任一部位均可代表全身的骨矿质含量，肱骨是确定全身骨矿质含量较好的部位，新生儿骨矿质含量受出生体重、孕龄及头围的影响较大。     

Rapidly growing calcified cerebellar astrocytoma in infants

We report the case of an infant with a cerebellar astrocytoma that showed marked calcification within only 6 months. In general, only slow-growing tumors tend to calcify. To our knowledge, no other case of such rapid calcification in cerebellar astrocytoma has been reported.     

改良超滤对婴幼儿心脏手术输血的影响

目的　观察改良超滤技术在婴幼儿体外循环心血管手术中对输血及术后出血的影响。方法　 6 0例接受体外循环下心血管手术的先天性心脏病患儿 ,均分为对照组 (不接受任何超滤 )、常规超滤组 (CUF组 )和改良超滤组 (MUF组 )。观察术中库血用量、血浆用量、血球压积的变化及术后2 4h出血量 ,并用SSPS/PC进行统计学处理。结果　MUF组库血用量、血浆用量、术后 2 4h出血量显著低于对照组和CUF组 (P <0 0 1) ,且滤出水量明显多于CUF组 (P <0 0 1)。结论　在婴幼儿心血管手术中 ,改良超滤可有效排出体内水分 ,提高血球压积 ,明显减少输血及术后出血 ,是节约用血的重要手段之一。     

CT检查对新生儿缺氧缺血性脑病预后判断的价值

目的　探讨CT检查对判断新生儿缺氧缺血性脑病 (HIE)预后的价值。方法　对 85例HIE患儿分别在生后 1周内、2周～ 2个月、3～ 6个月、1～ 1 5岁进行CT检查 ;同时在生后12～ 14d进行新生儿行为神经测定 ;在 1～ 1 5岁测定发育商判断预后。结果　生后 1周内CT结果分度为重度者预后不良率为 4 0 9% (9/ 2 2 ) ,为中度者预后不良率为 5 7% (3/ 5 2 ) ;2个月时CT随访结果异常者预后不良率为 6 0 0 % (6 / 10 ) ;CT结果中度且 12～ 14d的NBNA评分≥ 35分与 <35分者的预后差异无显著性 ,CT结果重度且 12～ 14d的NBNA评分 <35分者有 72 7% (8/ 11)预后不良。结论　生后 1周内CT分度及生后 1个月左右随访结果 ,同时结合临床、生后 12～ 14dNBNA评分对判断HIE患儿的预后、制定治疗方案及疗程有重要意义。
